0138-0252_EEDFileManifest.xlsx

This document is an Electronic Engineering Data (EED) File Manifest submitted by the Connecticut Department of Transportation for the Rehabilitation of Bridge No. 02150 in the Town of Stratford (Project Number 0138-0252). The manifest was prepared by Samuel Hopkins of Clough Harbor and Associates, LLP on July 21, 2026, and includes comprehensive engineering design files utilizing North American Datum 1983 (2011) and North American Vertical Datum 1988. The submission contains multiple CAD files organized by discipline, including survey data, hydraulic analysis, right-of-way information, access road design, existing and proposed bridge structure models, and sanitary sewer infrastructure. The deliverables encompass terrain models with 3D contours, FEMA flood line mapping, riprap basin design, alignment geometry, and bridge structural components including centerlines for bearings and girders.

The manifest is accompanied by a comprehensive Electronic Engineering Data Quality Control Checklist that verifies compliance with Connecticut Department of Transportation standards for the CTDOT Digital Design Environment (DDE). All CAD files are confirmed to be compatible with current departmental specifications, with elements positioned in real-world modified state plane coordinates and geospatially correct placement. The submission confirms that design models are free of extraneous construction lines, cross-sections, and annotation, with clean reference attachments containing only necessary files. All 3D files have been verified for proper elevation without irregular dips or spikes, and terrain models have been validated to ensure contours align with proposed drainage structures and that surfaces meet construction equipment tolerance requirements for automated machine control and guidance purposes.
